An isotope is an atom that has an irregular number of neutrons in its nucleus. Since it has the same number of protons as a normal atom, they still have the same chemical properties and are still technically the same thing, but since the atomic weight is different they have slightly different physical properties.

Which measurement would help determine absolute dates by radiometric means?
The measurement of the ratio of parent isotope to daughter isotope would help determine absolute dates by radiometric means. This ratio provides a way to calculate the age of a sample based on the known decay rate of the parent isotope into the daughter isotope.
How many neutrons are in the isotope in 1-h-1?
There is 0 neutron in a Hydrogen-1 isotope. Hydrogen-1 has an atomic number of 1, which means it has 1 proton and no neutrons.
17 neutrons and a mass of 32. What is the symbol of this isotope?
The isotope with 17 neutrons and a mass number of 32 has an atomic number of 15 (since mass number = protons + neutrons, 32 = protons + 17). This means it is an isotope of phosphorus, which has the symbol ( \text{P} ). Therefore, the symbol of this isotope is ( \text{P-32} ).
What is the opposites of an isotope?
The opposite of an isotope would be a pure element that does not contain any variations in the number of neutrons in its nucleus. This means that all atoms of that element have the same number of protons and neutrons.
Is oxygen-18 a common isotope?
Oxygen-18 is a relatively rare isotope, making up about 0.2% of naturally occurring oxygen. It is often used in scientific research, such as studying climate history through ice cores or tracking the movement of water in the environment. Its rarity compared to the more common oxygen-16 isotope means that it can provide valuable insights in various fields.
Which measurement would help determine absolute dates by radiometric means?
The measurement of the ratio of parent isotope to daughter isotope would help determine absolute dates by radiometric means. This ratio provides a way to calculate the age of a sample based on the known decay rate of the parent isotope into the daughter isotope.
Which percentage replaces letter x of the parent isotope per half-time of a radioisotope?
The percentage of the parent isotope remaining after one half-life of a radioisotope is 50%. This means that half of the parent isotope has decayed into the daughter isotope.
Isotope A has half-life of seconds and isotope B has a half-life of millions of years which isotope is more radioactive?
Isotope A is more radioactive because it has a shorter half-life, indicating a faster rate of decay. A shorter half-life means that more of the isotope will undergo radioactive decay in a given time period compared to an isotope with a longer half-life.
How many neutrons are in the isotope in 1-h-1?
There is 0 neutron in a Hydrogen-1 isotope. Hydrogen-1 has an atomic number of 1, which means it has 1 proton and no neutrons.
What does it mean when the isotope is fissile?
"Fissile" means "capable of undergoing fission."
In Adam that has 13 protons and 15 neutrons is an isotope of what element?
13 protons means it must be aluminum (Al). 15 neutrons means its atomic mass will be 28. This is not aluminum's most abundant isotope, but it is still aluminum.
What does it mean if a isotope is stable?
An isotope is considered stable if it does not undergo radioactive decay over time. This means that the nucleus of the isotope is not prone to breaking down and releasing radiation. Stable isotopes have a balance of protons and neutrons that make them resistant to spontaneous changes.
What is the mass number of the most common isotope in phosphorous?
Phosphorus-31 is the most common isotope. (Wikipedia)
What does a chain of radioactive decay ends with?
It must obviously end with a stable isotope - for if you get an unstable isotope, that means that it will continue decaying, thus, the chain doesn't end yet.
17 neutrons and a mass of 32. What is the symbol of this isotope?
The isotope with 17 neutrons and a mass number of 32 has an atomic number of 15 (since mass number = protons + neutrons, 32 = protons + 17). This means it is an isotope of phosphorus, which has the symbol ( \text{P} ). Therefore, the symbol of this isotope is ( \text{P-32} ).
What the difference between radioactivity and half life?
An isotope of a chemical element is an atom that has the same number of protons (this also means this atom has the same atomic number) and electrons, but has a different numbers on neutrons. The isotope is radioactive if it has too many neutrons in the nucleus and because of this the isotope is unstable. The half-life of a radioactive isotope is a time period. When the isotope is at the end of the period it's weight will be the half of the starter weight.
Argon has 18 neutrons in its nucleus?
That statement is incorrect. Argon has an atomic number of 18, which means it has 18 protons in its nucleus. The number of neutrons in an argon nucleus can vary depending on the isotope, but a common isotope, Argon-40, has 22 neutrons.
